What came first: the chicken or the egg? Beats me, but I can tell you that The Humble Android Bundle came first... and cutesy chicken-centric platform puzzler Toki Tori has now been added to it. It will be compatible with Windows, Linux and Android (hence the name of the bundle), and will already be available to download if you've already donated.
If you want to pay any amount of money for some great mobile games (compatible with PCs too) and give to charity at the same time, go ahead and check out The Humble Android Bundle for yourself. Note that there's room for a couple more games in the picture, though, and there's still time for further surprises.
